In a Thursday night speech in Las Vegas, Trump railed against lawmakers that he described as "blood suckers," bouncing from subjects like gas prices, Iraq, and foreign trade. "We have weak, pathetic leadership," Trump said of the Obama administration. "Our leaders are stupid, they are stupid people."

But that paled in comparison to his expletive-laden zingers on foreign policy and trade. Speaking about America's military presence abroad, he said:

We build a school, we build a road, they blow up the school, we build another school, we build another road they blow them up, we build again, in the meantime we can't get a fucking school in Brooklyn.

Then, on the issue of oil prices and OPEC, the coalition with control on much of the world's oil supply, he quipped:

We have nobody in Washington that sits back and said, you're not going to raise that fucking price.
